I could not find the answer you should call CZ at: 1-800-955-4486 or Phone: (913) 321-1811 Ext:4704

If you want open sights, then do not purchase this model. Purchase the 18.5" carbine that has good open sights. This specific model is on sale cheap due to the stock, which apparently was not a big hit with the firearm purchasing public.

Clarence, I wish CZ would include this info with their product. I would seek accurate info directly from CZ-USA Customer Service at Toll-free: 1-800-955-4486 or Phone: (913) 321-1811 Ext:4704 --- Representatives available Mon-Fri 9am-4pm Central
